THOMAS E. HUNT, OF BLUE ISLAND, ILLINOIS, ASSIGNOR TO QUAKER MANUFAC- TURING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

MACHINE FOR DISI-IING AND CORRUGATING METAL CAPS.

To all whom it may concern:

Be it known that I, TI-IoMAs E. HUNT, a citizen of the United States, and a resident of Blue Island, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Machines for Dishing and Corrugating Metal Caps, of which the following is a full, clear, and exact specification.

My invention is concerned with a novel machine for dishing or corrugating or both dishing and corrugating sheet metal disks or heads, and is designed to produce a device of the class described, which shall be simple in its construction and which shall be capable of operating on disks of a considerable size and thickness without requiring very great power to drive the machine.

To illustrate my invention, I annex hereto three sheets of drawings in which the same reference characters are used to designate identical parts in all the figures, of which:

Figure l is a side elevation of the machine; Fig. 2 is a vertical section on the line A-A of Fig. 1; Fig. 3 is a plan view in section on the line BB of Fig. 1; Fig. 4 is a top plan view of the roller carrier; Fig. 5 is an end elevation of the same seen in section on the line E,E of Fig. 4; Fig. 6 is a view of the same in vertical section on the line FF of Fig. 4; Fig. 7 is a plan view in section on the line GGr of Fig. 6; Fig. 8 is a perspective view of a head after the flange has been turned on it, but before the corrugations have been rolled; Fig. 9 is a perspective view of the completed head plate or cap; and Fig. 10 is a horizontal section through the same as it appears in position on the body of the furnace casing.

In carrying out my invention, I provide the feet castings 20, each of which is provided with bearings 21, in which is journaled the driving shaft 22 having the driving pulley 23 at one end and the speed-reducing pinion 24 at the other end. Secured upon these castings 20 are the channel bars 24, which have secured to their ends the end frame castings 25, upon the upper ends of which are secured the pair of channel bars 26, so that a rigid frame for the entire Inachine is thus produced. Journaled in suitable bearings 27 and 28 secured between the channel bars 24, and in a bearing 29 which may be secured to or form a part of the end Specification of Letters Patent.

Application filed July 15, 1907.

Patented Feb. 3,1914. Serial No. 383,820.

casting 25, is a shaft 30, which has secured on its outer end the gear wheel 31 driven by the pinion 24 and on-its inner end the bevel gear-pinion 32, which meshes with the bevel gear-wheel 33, to be more fully described. On the other side of the frame are provided a pair of bearings 34 and 35, corresponding to the bearings 27 and 28, and in these bearings is journaled a short shaft 36, which carries the bevel gear-pinion 37 which serves to support the other side of the bevel gear-wheel 33.

Bolted or otherwise secured between the channel bars 24 at the center thereof, as best seen in Fig. 2, is a bearing block 41, which has secured therein the bearing stud 42, upon which the hub 43 of the bevel gear-wheel 33 is journaled. This bevel gear-wheel 33 is provided with the plurality of radial spokes 44, and upon these spokes, toward the outer ends thereof, rest the legs45 of the head supporting disk 46, which is, of course, removable and changeable in order to enable the machine to be used in the manufacture of different sized head-plates or caps. The disk 46 is carefully adjusted concentric with the bevel gear-wheel 33, and secured in this concentric adjustment by the set screws 47, which are screwed through the sides of the grooved bottoms of the standards 45, as will be readily seen.

The positioning fingers 84, of which at least three mustbe employed, are secured to equi-distant supporting standards 45 of the disk 46 by any suitable means, as by the cap screws 85, the standards 45 being provided with threaded apertures 86 to receive these screws. The disk 46 is preferably concave, as shown, so-that a dished head may be formed upon it, if desired. These fingers, taking against the flange 59 of the disk 51, which is placed on the disk 46, serve to position said disk centrally of the apparatus and hold it from accidental displacement. The disk 51, shown in Fig. 8, has previously had the chine. The corrugating roller 87, which is best seen in Figs. 1, 5 and 6, has its periphery shaped to produce the desired corrugation, and it is journaled in the yoke 88 of a bearing sleeve 89, which is journaled in the bearing aperture 90 formed in the block 91, which is mounted to slide vertically in the block or casting 92, which is provided with the eight bearing ears 93, four at the top and four at the bottom, which ears support the bearing studs 94:, upon which are journaled the rollers 95 which bear on the horizontal. flanges at the top and bottom of the channel bars 20. The block 91 is provided with the under-cut groove 96 therein which receives the head 97 of the adjusting screw 98, which is threaded through the block 99 secured to the top of the block 92. It will be understood that this adjusting screw 98 is employed to regulate the height of the corrugating roller 87, and also that its vertical adjustment during the corrugating operation controls the concavity of the head-plate or cap when it is completed. I contemplate employing means for moving this block automatically during the corrugating operation to control the concavity of the head-plate or cap, but have not herein illustrated such means.

The bearing sleeve 89 for the corrugating roller 87 can be turned in its socket, this turning being permitted and the sleeve held in place by means of the screw 100, which is threaded through the block 91, and the end of which takes into the annular groove 101 formed in the upper end of the sleeve 89. To adjust the angle of the roller 87, and thereby the rapidity of its feed toward the center of the disk in the corrugating operation, I provide the screw 102, which is mounted to rotate in the lugs 103 projecting from the plate 10 1 secured to or formed integrally with the lower portion of the block 92, and this screw is threaded through the nut 105, best seen in Fig. 6, which is pivotally secured by the set screws 108 in the yoke 106 slidingly mounted in the yoke arm 107 pivoted outside of the yoke 88 on the bearing shaft of the roller 87. By operating this screw 102, it will be apparent that I can control the angle of the corrugating roller 87 relative to the radius of the disk 51 passing beneath the center of the roller,

46 and thereby control the rapidity with which the roller 87 will feed itself and its supporting block to the center of the disk 51 in producing the spiral corrugations 109, which I preferably produce. It will be understood that the rollers 95 are used to facilitate the movement of the corrugating-roller carriage on the tracks formed by the channels 26; and to further facilitate this movement, I preferably provide the additional rollers 110,

55 best seen in Figs. 4, 5 and 7, which are journaled in the ears 111 projecting from the sides of the block 92.

It will be understood that the roller 87 is set to the proper angle, and is then 50 screwed down upon the disk 51 just inside of the flange 59, and the apparatus is started. If the dished head-plate or cap of the design shown in Figs. 9 and 10 is to be produced, the screw 98 is turned down just rapidly enough to produce the desired dishing effect, so that when the roller has worked itself to the center of the disk, the metal will have been gradually drawn out into the dished shape shown and the corrugations simultaneously formed therein. It will be readily understood that this method of forming the corrugated head produces an extremely strong cap, as the metal is strengthened, not only by the shape of the corrugations, but also by the fact that they are rolled in, thus producing a head-plate or cap which, for the weight of the metal employed, is much stronger and superior to any heretofore produced with which I am acquainted.

It will, of course, be understood that if I merely wish to dish the head instead of corrugating it, I can do so by employing a wider roller 87, so shaped that it will merely dish the head instead of simultaneously dishing and corrugating it.

\Vhile I have herein disclosed a novel cap or head-plate, I do not herein claim the same, as that is claimed in my divisional application, No. 461,293, filed November 6, 1908.

\Vhile I have shown and described my invention as embodied in the form which I at present consider best adapted to carry out its purposes, it will be understood that it is capable of modifications, and that I do not desire to be limited in the interpretation of the following claims except as may be necessitated by the state of the prior art.

What I claim as new, and desire to secure by Letters Patent of the United States, is:

1. In a machine for impressing disks, the combination with a rotatable support upon which the disk is secured, of a carriage free to move transversely of the disk on the sup port, a corrugating roller in the carriage mounted to rotate freely, means for moving the roller in the carriage toward the disk to control the pressure of the roller on the disk, means for setting the roller to bring its axis at the desired angle to the line of movement of the portion of the disk engaged thereby, and means for rotating the support so that the roller will, due to the angle at which it is set, traverse a spiral path on the disk, moving the carriage in which it is mounted transversely to the disk, and indenting the disk according to the pressure put upon the roller, substantially as and for the purpose described.

2. In a machine of the class described, the combination with a supporting element, and means for rotating it, of a carriage for the cooperating roller, a cooperating roller mounted in said carriage, means for moving the roller in its carriage into engagement with the disk being operated upon, and means for adjusting the angle of the roller relative to the radius of the disk mounted in said arm.

3. In a machine of the class described, the combination with a supporting element, and means for rotating it, of a track, a carriage for the cooperating roller movable on said track, a sliding bearing block movable in said carriage transversely thereof, means for adjusting the position of the sliding block in said carriage, a bearing sleeve journaled to rotate in said sliding block, a 00- operating roller journaled in said sleeve, an arm carried by said sleeve, an adjusting screw, ears carried by the sliding block through which the adjusting screw passes, and a swiveled nut carried by said arm through which the adjusting screw is threaded.

In witness whereof, I have herein set my hand and aifixed my seal, this 10th day of July, A. D. 1907.
